(54) An alternating current machine


(57) An AC generator comprises a rotor 25 within a stator 24. The rotor carries a fan 27 at one end of the stator. The fan 27 is within a casing 30 which forms volute discharge passages 32. The fan 27 has blades 31 which project from the hub 28 at an angle which is oblique to the radial whereby those blades 31 trail the radial. The stator windings 23 form terminal leads 34 which are led from the end of the stator 24 remote from the fan 27. A circumferential array of cleats 35 which each have the form of a comb, support and guide the terminal leads 34 circumferentially, spaced from one another, to a certain location at the top from which the leads are taken and connected to terminals above. Those terminals are formed by the lower ends of busbars (56 to 58, 61 to 69) which extend through and which are supported by a structural panel of insulating material which forms an insulating barrier between the ends of those busbars. The upper end of each of those busbars forms the power output terminals U, V and W and the neutral terminals of the machine.
